Description

Structural laminated glass fins are engineered vertical support elements consisting of multiple glass layers bonded with polymer interlayers. These fins provide lateral support for glass facades while maintaining transparency. Available in standard thicknesses of 17.52mm (8.76+8.76), 21.52mm (10.76+10.76), 25.52mm (12.76+12.76), 31.52mm (15.76+15.76), and 39.52mm (19.76+19.76), using either PVB or ionoplast (SGP) interlayers for enhanced structural performance.

Glass fins emerged in the 1960s with monolithic tempered glass applications. The Apple Store Fifth Avenue cube (2006) popularized minimal laminated fin systems using ionoplast interlayers. Australian adoption accelerated post-2010 with improved AS 1288 guidance and local manufacturing capability. Current technology enables 15m unsupported spans with 50mm fin depths.
